NCT ID NCT07290829
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 52 soft contact lens wearers to see if a computer program (ImageJ) can measure eye redness more accurately than the standard grading system. The goal is to catch early signs of eye irritation. Participants wore lenses for two weeks and had their eyes checked with both methods.
